I am confused regarding significant figures. Consider "Calculate the volume of 2.8 kg of liquid with density of 1.11 g/cm^3"
Then, Volume = 2.8 kg * (cm^3 / 1.11 g) = 2522.522 (where 522 is recurring).
Since the original figure (2.8 kg) has only two significant figures, I thought the answer should be 2.5 kg.
The textbook says the answer is 2.523 kg, which is four significant figures.
Which is correct?
